We had a mix of window frames – teak single glazing in one part and aluminium single glazing in the other. The house was cold but we really didn’t want to change the window frames. Energlaze sent 2 different crews to our house. One team of carpenters worked on the teak windows and the other worked on the aluminium. They did an excellent job and we are really feeling the benefits.
